My inventionrelates to the sash construcf f tion' orholding the glassin place in a store frontconstrnctionand'it is my object to pro i vide simple, durable and` inexpensive vmeans for securing the glass, including, fa, pair of sash: membersto'xengage either ,side4 of ythe i 'glassA and a: tie-linkfor connectingthe two sash members, said link being operable from theouter'side ofl theA store front during installation by meanszof va lscrewdriver or the like.l

'More particularly itis :my objectv t0 `pro#V vide'L a constructionl including such tie u linkfthelength vbeingqso constructed and arranged relative to'thesashrmember ythat itv willfbe stoppedror llocked against further rotationvat acertain point: inl the process of s y y A from; the rear ofithe QutersaShJmember' connecting the sash members by-'means'of a link, whereby undue pressure cannot be imposed upon the glass betweeny the sashmembers by virtue of the driving of said link into connecting engagement'` with the: two sash members'.v y

More particularly referring to the last object it is my purposeto provide a .tiev linkv having a threaded engagement with bothv of the sashmembers which it connects-and a position adapted to engage one of the sash members to limit the rotationl oit the link relative to that member and to lockthe link by, wed 'ng of its threads against retrograde movement;

A still;furtherfobject isto provide an alr-v rangement in Aw-hich the link ywill t positively ymove the sash lmembers towardfeach other at a pre-determined rate'fasvthelink isv driven into its connectingengagement with the sash members', the parts being so arranged that when the linkhas been driven -to its limit vandthere stoppedby engagement of its cngagingportion with one'of the sashv members, thesash members will ihave approached to within a pre-determined distance t from eachiot'her in order toimpose upontheglass a' predetermined strain, whereby the amount of lstrain imposed upon the glass between the sashmembers yat each point otconnection willbe uniform.

With these and other objects iny view, i.

invention consists in the:l construction, `arrangement and comblnatlon of the'4 various parts'o-f my device; whereby thel obgectslcons from external sources.

It' is comin construction art that itnisv'desirable to con.- n y ynectthe sash members which holdy ay pane on knowledgefinthe store front ofgplate with a' small. amount of.. pres: sure'sucient to .y hold the glass -lirmly in placeyandyet not enoughto place the yarea .of glass surrounding the tie Alink vundera strain which will make thefglasssusceptible to splitting orflcracking in the Zone of strain whenI it is subjected to f librationorpressure Many-methodsghave been'devisedvof conynecting the sash- 5 members .sol that `the pres,- sure Vexerted. .upon they glass rmay beneglected lbut mostnf such y devices are r somewhat adapted to be engaged.

The glass 12 is ordinarilyv rested upon wooden blocks 13 and in the forms shown in Figs. 2 and 5 the shoulder 11 'forms one or the inter sash members for holding the glass.

In the forms shown in Figs. 4l, 8, and 10, an`

intersash member of sheet metal is pro-vided, having the vertical wall, 14, secured tothe shoulder, 11, by means ot wood screws, 15, a horizontal frame, 16, projecting forwardly and a forwardly bent portion, 17, terminating in a'. vertical flange to receive the glass.

The outer sash member comprises generally a molding having the ornamentalV wall portion 19 including a vertical portion, 20, to receive the tie iink, a. 'lower horizontal flange 21 to rest against the ledge 10 or the iiange 16 as thecase may be, and the interve-rtical flange 22 to engage the outer tace ot the glass. n

In Fig. 7 I have illustrated a horizontal dividing post, having an outer sash member comprising a channel shaped portion 23 and co-planar flanges 2a to engage the adjacent plates of glass on oneside.

rIhe inner saslimember comprises a plate 25 having inturned lianges 26 to engage the other sides of the-respective glass plates. At spaced intervals along the inner sash ineinber, brackets 27, having arms 23secured be tween the iia'nges 26 and plate 25 are provided in order to receive the threaded ends oi' the tie links. For this purpose the tie links are provided with threaded openings at 29. 'f i A In the forms of my invention shown in Figs. 2, 4, 5, and 7, I provide an arrangement in which the pressure to be had between the sash members is determined by manual pressure from the operator and in which the tie link does not, in itself, operate to rimpose pressure upon the glass but only preserves the hand ot the operaftoi. I accomplish this in a very simple nianner,the tie link being operable from the outer side of the sashby one hand of the workman and the pressureeXerted by the other one.

An'ordinary wood screw 30 may ne employed forr this purpose and in the 'forms 'shown in Figs.'2, 4 and 5 it is extended through the vertical portion 20 ofthe outer sash member and into the other shoulder 11. A small hole is drilled in the shoulder l1 in order to facilitate entrance of the screws and in order that the screw, at its inception, may not exert a back pressure against the manual pressure designed to give the sash members a grip upon the glass.

rIhe screw 30 has the ordinary slotted head 31 which, when the screw has been driven to the proper depth, will engage the vertical wall 2O of the outer sash member.

In order that such engagement of the head with the sash member may not add to the pressure imposed upon the glass, I pro vide for stopping the rotation screw iinmediately when the head has so engaged the wall 20. To this end I provide in Figs. 2

and i an L shaped bar 32 arranged opposite e each of the screw openings in the wall 2O and retained bythe iianges 16 and 22 in the manner shown.

rI`lie two legs of the bars 32 are sprung into place behind the flanges in such a way that the ends of the legs wiil engage the walls 22 and 22EL respectively and a bar thus firmly held in place. A' threaded opening7 33, is provided in the bar 32 and aligned with the respective screw opening.

Since screw 30 is threaded into the openi ing33, it will be seen that this thread engagement will serve to advance the screw relative to fthe sash member 19 rather than the thread engagement with the shoulder 11. This advancement will be stopped by the engagement of the hea'd 31 with the wall 2O and consequently the rotation of the screw will be also stopped and the screw may be wedged tightly against retrograde rotation by pressure rupon thescrew driver..

The bar 32 being ot' verysubstantial construction. the strain thus set up between thek bar and the lwall willr notfbend it.l This strain is tra-nsn'iitted directly by the horizontal leg bar to the wall 20. o 4

By stopping the rotation of the screw immediately when the head 31 has engaged the sash member it will be seen that this engagement will not serve to draw the sash member toward the shoulder 11.

Tere there no check upon the rotationoi the screw, it will be seen that further rotation after the head 31 has engaged the sash ineiny ber would drive the screw deepery intok the shoulder 11 and draw the sash members to.- ward each other.

In Fig. 5 the function of the bar 32is served by a sleeve 3lhavinga threaded por-l tion 35 and secured to the flange 21by means of integrally formed ears 36, as shownin Fig. 6.

In Fig.

37 similar to the bracket 27 rIhe yoke 37 has a threaded opening 38 to receive the screw. l

In Figs. 8 to 12 inclusive, I have shown a similar construction to that previously described in which the tie link or screw inem- 7 the bar 32 is replaced by aiyoke i ieaeezo l berrhas the. .added ffunction of' automatically 'determining the amount of pressure jt-0"'be .plac'eduponthefglass. l i Y ,In these forms of the invention thefunctionof the bar`32'is served by a fairly deep boss ...or collar '39 which may be drawn in- 'teg'rallywith the sash V`member '19 or Vformed .as a separatefbossswaged .into the wall-20.

The tie link lis'infthe form 'of a machine lscrewhavinga threadedfportion 40 adapted 20 and .havinga portion somewhat that .of the-.threads 40.

,A Aboss 43,.swaged into.- the portion 14a of the rear wall 14,` has a threaded bore 44 to receive the threaded portion 42 of the screw.

25 3 .'Inaassembling `the store front the two .casingmembers are placed ina p'arallelposition with :the .glass between them and with the screw members of 'the tie links entirely fremoved.

V...3c .such .a 'way'.that the Athreads '42 and 40zwill .enter their respective thread openings at the -1- Sametime. y

f. It'fwill now'be seen that when the screw yhas been drivenhome' the samev number of .Q lthreads of the screw fportion 42.- and 40 relspectively will vhave entered uthe .boss 43.and vcolla-r y39 respectively and Ithat 'during this i' entrance .the collar 39 will! have been moved r toward the boss 43 a distance corresponding vtothe dii'erence'dn pitch of the respective `threads multipliedv bythe number of threads y l'which have entered. rIhis diierence in pitch is made very slight and the length of the sore-wis regulated softhatiwhen vthe screw is 'l readyfuto enteimboth .boss V43 .andcollar 39 y simultaneously'the member V19 will be in` very close proximity to the glass whereby a very slight ramount of adjustment of the member 19 will cause it to grip the glass.

By making the necessary lmovement between the members small it will be seen that any inaccuracy of yadjustment which may bev encountered ley-reason of one of the threads 42 or 40 being started in its respective opening ahead of theother, will be correspondingly reduced.

In the forms shown in Figs. 10, 11, and l2 the screw member of the tie link has one of its threads 40a formed on its exterior and its Y 'tionwitlrfthe screw v40 or 40aLpreventsthe 'screw 'beingrotated beyond the point :where the sash-memberslare properly spaced Iin f having the outer sashy member'25a, jthe "bracket 27a secured "by= the fffla'nges 26agan'd ,v
